Hooker Huw Bennett has urged the Wales pack to back up its impressive showing against South Africa when they face World Cup rivals Samoa next Sunday.

Wales limited the Springboks to just 40% possession in Wellington, which compounded the agony of their 17-16 Pool D defeat.

"We've done a lot of work on our fitness and we've worked a lot on the contact area, so I expected us to be competitive," said Bennett. "But it was nice to hear that we had 60% possession because we don't usually enjoy that much ball against these type of teams. In fact, I would be surprised if we have ever won that much ball against South Africa, but it has got to be backed up now."

Samoa launch their World Cup campaign against Namibia in Rotorua on Wednesday and are viewed as serious threats to both Wales and South Africa, with just two quarter-final places up for grabs.

"There will be no complacency against Samoa," Bennett added. "We know their strengths and the quality they possess.

"It's also World Cup time and sides like them have a lot of time together, so they are potentially very dangerous.

"We know we will have to be on our mettle. They are a quality outfit who have played well this year, so we will have to be on top of our game."
